Tikkun Chatzot

The midnight rite, at the right moment, wherever you are.

Chatzot halayla moves every night, differs by where you are, and is almost never midnight on the clock. This app removes that problem. Set your location once. Every night it works out chatzot for exactly where you are, wakes you at it, and has the text waiting when you get up.

The right time, and the working shown

Chatzot halayla is calculated as twelve hours after chatzot hayom — the reckoning of the Baal HaTanya (Shulchan Aruch HaRav, Hashkamat HaBoker 1:8). The app shows the whole derivation, sunrise through chatzot halayla, so it can be checked against a printed luach rather than taken on faith.

The text

Tikkun Rachel in Nusaḥ ha-Ari, in the order of the Siddur Torah Ohr of Rabbi Shneur Zalman of Liadi, in Hebrew and English. Built for reading at one in the morning: dark from edge to edge, large adjustable type, and the screen stays awake.

Nothing leaves your phone

No account, no sign-in, no analytics, no server. Your location, your intentions and the nights you mark as kept stay on the device. The app works with no signal at all. See the privacy policy.

It is, however, appropriate for anyone who is G-d-fearing, and all people of valor whose heart has been touched by Hashem, to rise at midnight and devote a little time to mourning for the destruction of the Holy Temple and the exile of the Divine Presence.

— Shulchan Aruch HaRav, Hashkamat HaBoker 1:2
The mourning should not be confined to Tisha B'Av alone. Instead, every person should engage himself in crying and lamenting over the destruction of the Bais HaMikdash every night at midnight.

— The Yanuka, The Way of the Tree of Life, translated by Rabbi Harry Rozenberg

Rabbi Rozenberg has translated the sefer in full on YouTube, including the teaching on Tikkun Chatzot that the app quotes.

Where practice is uncertain, ask a rav — not an app.
